Terax is a fast, lightweight AI terminal (ADE) built on Tauri 2 + Rust and React 19. It pairs a native PTY backend with a modern UI — multi-tab terminals, an integrated code editor, a file explorer, and a first-class AI side-panel that works with your own API keys (or fully local models via LM Studio). Under 10 MB on disk, no telemetry, keys stored in the OS keychain.
